Abstract

In separating solids from a liquid by settling or flotation, the liquid is made to flow generally horizontally through a tank, and means at the inlet or outlet zone of the tank impose a velocity gradient on the flow. In settling, the velocity increases upwards in the tank (Fig. 3), and in flotation the velocity will decrease upwards to enhance separation. Fig. 3 shows a baffle with holes of various sizes at the inlet, but other embodiments involve equivalent means at the outlet zone, namely a single annular baffle with holes of various sizes (Fig. 6) and arrays of vertical outlet tubes with holes of various sizes (Figs. 4, 5) and internal divisions and overflow weirs (Figs. 7, 8). <IMAGE>
